Need tips for the next tool to buy to complement my software?

hey folks,

I've been thinking what the next software / service purchase for link building should be that makes sense in addition to what I already have... I'm a bit undecided so if you guys could point me into the right direction that would be cool...

What I do have:
Scrapebox
AMR
SEOLR

What I do not want to buy:
Xrumer
Senuke

I was thinking about UAW for more link domain diversification(but I don't like the monthly fee, the question is if it pays off...), Bookmarking Daemon for same reasons but those links will probably not give much link juice...

Magic submitter unfortunately has a monthly fee too... Any other tools or affordable services that give me a lot of different IP's to link(best would be through content links) to my site that are worth mentioning?

The automated link pushing service on BHW is also on my watchlist.

Thanks for any feedback guys...
